AI Technical Summary

Benefits of technology

The anchor sleeve effectively secures therapy delivery elements by facilitating deformation of the inner sleeve to engage the element firmly, reducing migration risks and allowing for secure attachment to tissue, thereby maintaining therapeutic efficacy and minimizing side effects.

Problems solved by technology

Retaining the implanted therapy delivery element in the desired location also creates difficulties because the location may change over time as the patient moves.

Embodiment Construction

[0029]The description that follows relates to a spinal cord stimulation (SCS) system. However, it is to be understood that the while the present disclosure lends itself well to applications in SCS, the disclosure in its broadest aspects may not be so limited. Rather, the disclosure may be used with any type of implantable therapy delivery system with one or more therapy delivery elements. For example, the present disclosure may be used as part of a pacemaker, a defibrillator, a cochlear stimulator, a retinal stimulator, a stimulator configured to produce coordinated limb movement, a cortical stimulator, a deep brain stimulator, peripheral nerve stimulator, microstimulator, or in any other neural stimulator configured to treat urinary incontinence, sleep apnea, shoulder sublaxation, headache, etc.

[0030]In another embodiment, one or more of the therapy delivery elements may be a fluid delivery conduit, such as a catheter, including an inner lumen that is placed to deliver a fluid, suc...

Abstract

An anchor sleeve for securing a therapy delivery element, such as a stimulation lead or catheter, within a living body, that includes an inner sleeve with pre-formed locations of weakness that facilitate localized deformation. The anchor includes a deformable outer sleeve with a primary lumen extending along an axis. The outer surface of the outer sleeve includes a plurality of suture grooves oriented generally concentric to the axis. The inner sleeve includes a plurality of beams connected at deflection regions arranged around a secondary lumen. The inner sleeve is located in the primary lumen adjacent to the suture grooves so that the secondary lumen is generally concentric with the primary lumen. A plurality of locations of weakness are preformed in each of the beams to facilitate localized deformation in response to a radially inward force applied around the suture grooves by a suture material.

Description

FIELD[0001]The present disclosure relates to an anchor sleeve for securing a therapy delivery element, such as a stimulation lead or catheter, within a living body. The anchor includes an inner sleeve with pre-formed locations of weakness that facilitate localized deformation around the therapy delivery element.BACKGROUND[0002]Implantable medical devices are used for a wide variety of medical conditions, such as for example, cardiac pace making, cardiac rhythm management, treatments for congestive heart failure, implanted defibrillators, and neurostimulation. Neurostimulation encompasses a wide range of applications, such as for example, pain control, nervous tremor mitigation, incontinent treatment, epilepsy seizure reduction, and vagus nerve stimulation for clinical depression.[0003]These implantable medical devices generally include an implanted pulse generator that generates electrical pulses or signals that are transmitted to a targeted tissue or nerves through a therapy delive...
